One thing prevent our company to upgrade to newer labview is that the run-time engine gets too big. Even I really like the features in later version, I still have to save the files back to 7.1 then to 7.0 to build application installer. Under 7.0, the run-time engine is very small, and the installer is less than 10MB and I can easily email the program to customers. In version 8.0, the run-time engine is 65MB and now the latest version is well above 100MB.
What I would like to see is that application builder get smart, only pick what is needed and build slim app.
